WHEEL-PRESS TAIL-BLOCK.

Serial No. 799,923.

To all whom it may concern:

Be it known that I, Gnonen T. Rniss, a citizen of the United Stat-es, residing at Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in WVheel-Press Tail-Blocks, of which the following is a specification.

In ordinary hydrostatic wheel-presses when a wheel is to be removed from an axle the axle is passed transversely into the gap in the tail-block and the hub of the wheel is rested against the inner end of the tailblock, the ram of the press then engaging the projecting axle and pushing it out of the wheel. Wheels which have been long on axles often require more power for re moval than was originally required in pressing the wheel to place upon the axle. The form of the gap in the tail-block is necessarily such that the hub of the wheel in bearing against the face of the tail-block has but a partial bearing around the axle, the result often being that with the very heavy pressures often required in removing wheels, the hubs of the wheels, as well as the face of the tail-block, become more or less mutilated. Furthermore, the gap in the tail-block must be large enough for the largest axle the press is to deal with, the result being that in removing old wheels from axles the bearing of the wheel-hub against the face of the tailblock is an undesired radial distance from the axle, in addition to the bearing being but a partial one, circumferentially considered.

My improved tail-block provides for a complete bearing of the wheel-hub all the way around the axle and it also provides for contact between the wheel-hub and tailblock close down to the axle.

An ordinary hydrostatic wheel-press of a character in which the present improvement may be embodied or to which it may be applied will be found set forth in Patent No. 843,098 granted February 5th, 1907, to Niles- Bement-Pond Company on the application of the present inventor. The wheel-press of that patent is set forth as being provided with an improved device for pressing car wheels from an axle in cases where a gear is secured to the axle behind the wheel which is to be removed. In the use of such a press, ignoring the additional features for dealing with a wheel on an axle having a gear, the axle is placed in the gap of the tail-block with the hub of the wheel resting against the inner face of the tail-block, and the ram of the press is caused to engage the projectlng end of the axle and push it back out of the wheel.

block with the head-block of the press: 3,-

disposed against the face of the tail-block, W

the axis of the thrust-collar coinciding with the axis of the gap in the tail-block: 6, bolts serving as means for securing the half-collar 5 to the tail-block if the half-collar be made separable from the tail-block: 7 the second half of the thrust-collar, this second halfcollar joining the first half-collar at a ver tical line of separation and being movable relative to the first half-collar: 8, a hinge disposed below the two half-collars and uniting them: 9, a buckle-bolt engaging the upper portion of the two half-collars and serving to tie them together: and 10, diametrically divided bushing disposed in the bore of the collar.

It will of course be understood that the face of the tail-block provided with the thrust-collar is the face opposing the headblock of the press. When a wheel is to be pressed off of an axle the front half-collar 7 is to be unbuckled and swung down leaving open, not only the gap in the body of the tail-block but also the bore of the thrustcollar. The axle having been entered transversely into the gap, the front half-collar 7 is turned up to working position and buckled to the rear half-collar. The ram of the press is then to operate as usual on the projecting end of the axle and push it out of the wheel while the inner face of the hub of the wheel bears against the face of the thrust-collar. In this operation the thrustcollar bears upon the inner face of the hub of the wheel entirely around the axle.

It is desirable under the conditions mentioned in the early part of this specification,

that the thrust-collar bear against the inner time to remove a given thrust-collar and replace it by another one so that the rear half of the substituted thrust-collar becomes a rigid portion of the tail-block. The bushing 10, being free to slide in the thrust-collar, does not offer a resisting thrust surface but the bushing is of advantage in centering the axle in the thrust-collar. In most all cases the wheel-seat of an axle is larger than that portion of the axle just inward of the wheel-seat, and in employing the bushing the axle may be fairly centered in the thrustcollar when the axle is placed in the press and, when the axle begins to move out of the wheel, the wheel-seat may force the bushing out of the thrust-collar and into the gap in the body of the tail-block, the wheel'- seat entering the bore of the thrust-collar and permitting the inner face of the hub of the wheel to take fair bearing against the face of the thrust-collar all around the axle and close to the axle.

I claim V 1. A wheel-press tail-block comprising, a gap in the front of the body of the tailblock, a rear fixed thrust-collar-half fixedly secured to thethrust-receiving face of the tail-block at the rear of the gap therein, a front movable thrust-collar-half adjoining the first-mentioned half and bearing against the face of the gapped portion of the body of the tail-block, and means for securing the two halves of the thrust-collar together, combined substantially as set forth.

2. A wheel-press tail-block comprising, a gap in the front of the body of the tailblock, a rear fixed thrust-collar-half fixedly but separably secured to the thrust-receiving face of the tail-block at the rear of the gap therein, a front movable thrust-collar-half adjoining the first-mentioned half and bearing against the face of the gapped portion of the body of the tail-block, and means for securing the two halves of the thrust-collar together, combined substantially as set forth.

3. A wheel-press tail-block comprising, a gap in the front of the body of the tailblock, a rear fixed thrust-collar-half fixedly secured to the thrust-receiving face of the tail-block at the rear of the gap therein, a front movable thrust-collar-halfadjoining the first mentioned half and bearing against the face of the gapped portion of the body of the tail-block, a hinge disposed at the lower portion of the thrust-collar and uniting the two halves below the bore of the collar, and means disposed above the bore of the collar for binding the upper portions of the two halves together, combined substan tially as set forth.

A Wheel-press tail-block comprising, a gap in the front of the body of the tailblock, a rear fixed thrust-collar-half fixedly secured to the thrust-receiving face of the tail-block at the rear of the gap therein, a

front movable thrust-collar-half adjoining the'first-mentioned half and bearingagainst the face of the gapped portion of the body of the tail-block, means for securing the two halves of the thrust-collar together, and a diametrically divided bushing disposed within the bore of the thrust-collar, combined substantially as set" forth.
